Application led October 9 To all whom it may concern:

Be it known that l, BnNJAMiN S. SrnrnnN- Y SON, a citizen of the UnitedStates, and a resident of Brooklyn, in the county of Kings and State ofNew York, (whose )ost-ofiice address is U6 Montagne street, rooklyn, NewYork,) have invented certain new and useful Improvements in Surgical`instruments, of which the following is a full, clear, and exactdescription, whereby any one skilled in the art may make and use thesame.

The invention relates to implements for use in connection with avibrating mechanism for securing a treatment and cure of hy ertrophicaltissuesof the human4 body and diseased or abnormal'parts. y

it relates particularly to implements adapted to be used with avibrating mechanism for securing a Vscarifying action upon diseasedtissue or tissues needing treatment.

The object of the invention is to provide a simple, economical andeffectivewimplement for treating portions of the human body without theuse of the lancet or knife, and has for a ment, by scari cation, ofaffections of the mucous membrane.

A further object is to provide an implement which will be eiiective,through its scarifying or crimping action, to cure through externalmeansl affiictions of the mucous membrane, thus vavoiding attendantdangers of anesthesia and operations by the knife, snare, cautery orcurette.V

A further object is to provide an implement or implements which in.connection with a vibratory mechanism and manual operation may be usedfor successful treatment of adenoids, enlarged tonsils, turbinates andpolypoid growths, as well as for uterine treatments.

Referring to the drawings: Figure l illustrates one form of device,articularly adapted for the treatment of en arged tonsils illustrated asYapplied to a vibrating mechanism. Fig. 2 shows a similarvibratorymechanism with an implement of the proper form to treat turbinates andpolypoid growths. Fig. 3 illustrates the effect of the' instrument inuse upon any tissue. Fig. 4 illustrates the instrument in roper form forthe treatment of adenoids or growths in the throat or larynx;v llig.` 5is Specification of Letters Patent.

a detailed view of the instrument illustrated in connection with l forthe treatment of enlarged tonsils. Fig. 6 is a modified form of theinstrument illustrated in Fig. 5. Fig. '7 is adetailed view of theinstrument employed in the treatment of enlarged turbinates and polypoidgrowths. This instrument is further illustrated in 2 in Fig. S shows oneform of an instrument suitable for use in uterine treatments. Fig. 9 isa cross sectional view through the scarifying bur.

-Many diseases or instances of hypertrophical tissue are usually andordinarily operated upon surgically by cutting or scraping, and it isthe object of the present invention to produce a means for avoiding suchcutting yor'scraping operations and to cure or benefit the diseasedtissues by vibratory scarifying implements.

The implement is so constructed as to have a peculiar crimping actionupon the tissue when used, and whether or not it actually cuts thetissue or merely crimps it, as might be done in certain cases, itsaction is most beneficial. The scarifications are so minute and frequentthat they act substantially as an intense counter-irritant which causesa puckering or contraction of the afflicted tissuesiwhich ultimatelycontract and are reduced to a normal condition without removal of anysubstantial part thereof by a knife.

The invention consists essentially of a bur a which is preferably ofsubstantial elliptical form and has runnin@ from end to end thereofsubstantially paralel with its axis b a series of scarifying edges c.This bur, as illustrated in all instances except in Fig. S, is rotarilymounted on its pivot or axis t in the bifurcated end d of a handle e.The handle is arranged to be secured to any suitable vibratingmechanism, such as illustrated somewhat in diagram at f.

As herein shown in Fig. l the vibrator consists of a set of electromagnets g acting on an armature g/ to effect a movement of the handle ewithits scarifying bur a axially of the axis of said bur and in linewith the cutting edges or teeth c. The vibratory movement in Figs. 1 and2 is indicated by the arrows.

Of course it is understood that the vibrator gives almost an infinitenumber of vibrations within the shortest periodof timemand of course thenumber or frequency of tlie vibrations may be varied to suit tlieexigencies for any case. Figs. l and 2 are merely illustrative of thedirection oi vibration of the scariying roll or bur.

ln Fig. 8 the bur, as illustrated, is inounted upon a pivot extendingfrom the end of the handle, and in Fig. 6 the bur is illustrated as oielliptical forni with very slight cutting teetli. ln fact, for treatmentin sonic cases the teetli inay be rnade liardly appreciable, and yetwhen used in the instrument with a )articular nietliod of vibration,herein deiined, Will be effective for crimping the tissue to the desireddegree to secure proper stimulation and shrinkage.

ln Fig. 3 an attenipt has been rnade to illustrate tlie peculiar actionot tlre instrurnent upon the surface to be treated. Of course in usetlie instrument is rapidly vibrated axially of the bur and While sovibrated is rolled over tl e ailected tissue, the result is a distinctangular scariiication, as illustrated in 3, Wliiclr may be increased ordecreased at tlie will or the o ierator.

Attention is called to the pecu iar eilect ot tlie rapid vibrationsaxially of the bur coinbined with a rolling rncveinent performed bytlie' operator transverse to the axis oi the roll. lf the bur is merelyrolled by the operator overtlie surface on its axis, there is not thesame transverse cutting ei'lect as secured by suoli a rolling actioncombined with a very rapid axial vibratory Inovenient-in fact, it

is tlie conibined movements upon the instrutrated in the accennianying`d rawing/s, and ol" course it is understood that the instrument may beapolied to any desired affected part and niust )e of suoli a forni asinay be inserted within a particular passagyje ol the body requiring`treatment. varied for any particular passage and the location oi' thetissue to be treated.

in practice the various parts ol tlxe instrunient sliould be inade of ametal suitable to be effectively sterilized.

lliat i claini as niy invention and desire to secure by Letters Patentis:

l. A searilier consisting ci a handle, and a scariiyino` bur rotarilymounted therein and provided With. line cutting',- teeth.

2. A scarilier consisting ol a handle, a scarifying` bur rotarilvinounted therein, and provided with cutting; teeth, and nieans forvibrating;y said bur in tlie direction of its axis.

3. A scarl ying` instrument eoniprisiiu: a handle, an elliptical rolljournalcd to rotate in said handle, cutting teeth extending; from end toend oi said roll, and ineens for vibrating said roll in an fr raldirection. BENJABHN S. STEPHENSON. Vi/Titnesses Gonmnr N, NELSON, ALICElv PARKER.
